2. Key facts

U.S. Department of Agriculture, Agricultural Research Service. What We Eat in America, 2017-2018. 2020. The evidence for a relationship between vitamin B12 and cancer risk is mixed. Some evidence supports a link between increased cancer risk and higher intakes or blood concentrations of vitamin B12, some supports a link with lower intakes or concentrations, and some evidence indicates no link at all. U.S. Food and Drug Adminstration. Code of Federal Regulations Title 21 § 107 -- Infant Formula. 2019. Because the body stores about 1 to 5 mg vitamin B12 (or about 1,000 to 2,000 times as much as the amount typically consumed in a day), the symptoms of vitamin B12 deficiency can take several years to appear [ 7, 33].

Prescriptions must be written on an Authority Prescription Form, and the approval number must be noted on the prescription. Pharmacists cannot dispense the item as a pharmaceutical benefit unless it has been approved by Medicare Australia (indicated by the presence of the approval number).

[ PubMed abstract] Vegans who consume no animal products and vegetarians who consume some animal products (e.g., dairy products, eggs, or both) but not meat have a higher risk of developing vitamin B12 deficiency because natural food sources of vitamin B12 are limited to animal foods [ 3, 55]. Consumption of foods fortified with vitamin B12 (such as fortified nutritional yeasts) as well as vitamin B12 supplements can substantially reduce the risk of deficiency [ 55].

[ PubMed abstract] Research suggests that vitamin B12 supplementation might also help lower levels of homocysteine, an amino acid that may be linked to an increased risk of heart disease. An elevated homocysteine level has been associated with an increased risk of CVD [ 72, 73]. Vitamin B12 and other B vitamins are involved in homocysteine metabolism, and researchers have hypothesized that supplementation with these micronutrients can reduce CVD risk by lowering homocysteine levels [ 72, 73].

Your body requires vitamin B12 to make red blood cells. You can get it from your food or supplements, but sometimes there may not be enough vitamins in what you eat. This can happen if you are vegan or you do not eat much meat or dairy products. Another dose-finding trial study shows that the lowest daily dose of oral cyanocobalamin required to normalize the biochemical markers of mild vitamin B12 deficiency varies from 647-1,032 mcg in the elderly.The FNB did not establish a UL for vitamin B12 because of its low potential for toxicity [ 1]. Even at large doses, vitamin B12 is generally considered to be safe because the body does not store excess amounts. Interactions with Medications

Cancer Epidemiol Biomarkers Prev 2019;28:275-82. [ PubMed abstract] When there are multiple B vitamin deficiencies I typically recommend seeking out a B complex,” says registered dietitian Jenna Volpe. The Designs for Health B-Supreme is a quality supplement that is NSF certified, a third-party agency that tests for purity and accuracy of the label. It contains methylcobalamin, an active form of B12 that may be better absorbed by the body than cyanocobalamin (though more research is needed). Limited clinical trial evidence supports the finding that higher vitamin B12 intakes might increase cancer risk. In an analysis of data on 2,524 participants in the B Vitamins for the Prevention of Osteoporotic Fractures trial who were treated with supplements containing 400 mcg/day folic acid and 500 mcg/day vitamin B12 for 2 to 3 years, the risk of colorectal cancer was significantly higher, at 3.4%, in the supplementation group than in the placebo group, whose rate was 2% [ 61]. However, high folic acid levels are potentially linked to increased risk of colorectal cancer, so the result might be due to the folic acid rather than the vitamin B12 [ 62]. Furthermore, the supplements had no significant effect on overall cancer risk.

There are very few reasons to take supplements, but getting enough of this vitamin may be one of the most important.

Vitamin B12 is a water-soluble vitamin that your body uses for various processes, including energy production, DNA synthesis, and the development and function of your central nervous system. However, 1000 mcg daily dosing of cyanocobalamin was able to normalize the MMA concentrations in patients with pernicious anemia.
